LUBRICATOR FOR RAILWAY JOURNAL BOXES.

Application led October 9, 1925. Serial No. 61,432.-

This invention relates to lubricating devices and is particularly adapted to be used in railway journal boxes.

The primary object of thev invention is to provide a reservoir for oil which can readily be inserted into a standard railway box or removed therefrom and which contains means for conveying oil within the reservoir to the journal as well as means for closing the topof the reservoir so as to prevent dirt and water from getting therein and to retain the oil therein except when it bears against the journal.

These and other objects, as will hereinafter appeal', are accomplished by this nvention which is fully described in the following specification and shown in the accompanying drawings, in which:

Figure 1 is a vertical longitudinal section 2o through a railway journal box enclosing the lubricating device;

Fig. 2 is a transverse' vertical section on the line 2 of Fig. l;

Fig. 3 is a top plan view ofthe lubricator removed; and

Fig. 4 is a similar view with the felt covering and supporting shoe removed.

The embodiment illustrated shows a standard railway journal 10 enclosed in a standshown in'Fig. 2, is normally pressed upwardly toward the journal by means of coil springs or the like 17. Overlying the shoe 16 is a pad 18 of felt or the like which extends over substantially the entire top of the reservoir 15 and is secured around the edges vthereof by means of a band 19 which is riveted or otherwise securelyfastened thereto so that dust and Water are prevented from falling into the reservoir 15.

Strips of wicking 20 or the like are secured to the upper surface of the shoe 16 and in contact with the felt 18. These extend into the bottom-of the reservoir 15 so that when ard railway journalbox 11 having an open-` For convenience in inserting the lubricator into a journal box a flexible wire cord or the like 24 is attached by mea-ns of an eyelet 25 to the bottom of the shoe 1.6, the cord passing through a tube 26 which is secured to the bottom of the reservoir 15 and leads out to the'upper forward corner. 4A button 27 is secured on the outer end of the cord 24.

Thus, to remove the lubricator, the'operator grasps the outer portion 21, at the same time pulling up on the button 27. This draws the shoe 16 down' compressing the springs 17 so that the lubricator can then be readily withdrawn from the journal box.

The pad 18 feeds oil at the point Where it makes contact with t-he journal while at the sides and' ends where no contact occurs it retains the oil and at the same time keeps out dust and water, thereby keeping the oil vsupply pure and clean.

Buttons 28 of hard. rubber, libre, or the like, are placed at intervals about the reser- 1voir to prevent undue chafing in the ournal While I have shown and described but a single embodiment of this invention, it is to be understood that it is capable of many modifications. Changes therefore in the construction and arrangement may be made which do not depart from thespirit and scope of the invention as disclosed in the appended claims.

I claim:

1. In a lubricator for ,railway journal boxes, an oil reservoir adapted to pass into and out of a journal box, an imperforate oil transmitting pad adapted to contact the under side of a journal and flexibly connected to said reservoir so as to seal the' top of the same, and means within said lubricator for yieldingly'holding said -pad in contact with said journal when in the journal box.

2. In a lubricator for railway journal boxes, an oil reservoir adapted to pass into and out of a journal box, an imperforate oil transmitting pad adapted to contact the under side of a journal and flexibly connected to said reservoir so as to seal the top of the same, means Within said lubrieator for yieldingly holding said pad in Contact with said'journal when in the journal box, and an extension on said reservoir adapted to maintain oil above the level of said pad.

3. In a lubrieator for railway journal boxes, an oil reservoir adapted to'pass into and out of a journal box, an oil transmitting pad adapted to Contact the under side of a journal and flexibly connected to said reservoir so as to close the top of the same, wicks opel-ably connected to said pad for feeding oil from the bottom of said roservoir, and means Within said lubrieator for yieldingly holding said pad in Contact with said journalwhen in the journal box.

4. In a lubrieator for railway journal boxes, an oil reservoir adapted to pass into and out of a journal box, an oil transmitting ,pad adapted to Contact the under sideof a journal and fiexibly connected to said reservoir so as to close the top of the same,

' .means for lyieldingly holding said pad in Contact With said journal when in the journal box, and means operable rom the front of sald journal box for depresslng said yielding means during insertion or Withdrawal of said reservoir.

5. In a lubricator for railway journal boxes, an oil resevoir adapted to pass into and out of a journal box, an oil transmitting pad adapted to Contact the under side of a journal and flexibly connected to said reservoir so as to close the top of the same, means for yieldingly holding said pad in Contact with said journal when in the journal box, and a fiexible member operable from the front of said journal box for depressing said yielding means during insertion or Withdrawal of said reservoir.

6. In a lubrieator for railvay journal boxes, an oil reservoir adapted to pass into and out of a vjournal box, an oil transmitting padadapted to Contact the under side of a journal and flexibly connected to said reservoir so as to close the top of the same, a frame having substantially the curvature of said `journal lying beneathv said pad, and means Within said lubricator for yieldingly holding said pad in Contact with said journal when in the journal box.

7. In a device of the Character set forth, a stationary oil reservoir adapted to pass into and out of a journal box and adapted to .be supported by a journal box, an oil transmitting pad adapted to contact the underside of a journal and flexibly connected to said reservoir so as to close the top of the same, and means Within the reservoir for yieldingly holding said pad in Contact with said journal when in the journal box.

8. In a device of the character set forth, a removable oil reservoir adapted to be supported in Contact With a journal box, an oil transmitting pad adapted to contact the underside of a journal and flexibly connected to said reservoir so as to seal the top of the same, and means for yieldingly holding said pad in Contact With said journal When in the journal box.
